Most Helpful Negative Review good product but used
Love the product, but the slide and compensator were used. The slides optic cutout plate screw head was stripped and the compensator had burns and powder buildup. Inside, carbon buildup at the firing pin. New barrel and spring, though!

Spectre Comp Slide

by bourbondrinkernotathinker, Verified Owner from WI, United States Written on February 19, 2025
Works great and I am much more accurate with this. I did have some stovepipes with 115 grain ammo. 124 and 147 ammo ran perfectly but only have 75 rounds through it. Hopefully it breaks in.

Awesome setup

by Aaron Mcdonald, Verified Owner from CA, United States Written on February 1, 2025
All in one package, just put it on your grip module of choice and you’re ready to rock! 20lbs is the torque specifications for the compensator. Add a little blue loctite to screws
Pros:
  • Recoil spring already tuned
Cons:
  • None

Dirty/used/returned item

by DAMOND, Verified Owner from VA, United States Written on September 4, 2024
This is clearly a used slide. Factory testing does not get this dirty and the side serrations do not get dirty. They could have at least cleaned it up out of courtesy!
Pros:
  • Price
Cons:
  • Used
